Is spotpass being planned on being worked on for pretendo on the 3ds? If so will there be functionality for the mii travelers to come back home after a while for tomodachi life (or possibly send letters)? I’m also wondering if there will be spotpass things like special pretendo items rolled out for different games that support spotpass?
SpotPass already is implemented in a limited sense for 3DS notifications.
We plan to use it for other purposes like the ones you’ve mentioned eventually.
